This analysis estimates the potential impact of extending marriage rights to same-sex couples on Maryland's state budget. Drawing on data from the U.S. Census Bureau and Maryland statistical reports, we estimate that extending marriage rights to same-sex couples would result in a net gain of approximately $3.2 million each year. This net gain is attributable to savings in expenditures on meanstested public benefit programs and an increase in sales and lodging tax revenue from weddings and wedding-related tourism.
